SAJ
Established string inverter specialist — strong value with R5 series.
SAJ has been making inverters since 2004 and is one of China's longest-running power-electronics specialists. The R5 series is a clean, no-nonsense string inverter range that's earned a quiet but loyal Victorian following thanks to reliable performance, built-in WiFi monitoring, and great value at the entry-tier-1 price point. A solid pick when budget is the priority but warranty support still matters.
